' My present invention relates to apparatus for blending solid substances with liquids, particularly in the presence of liquids nomically fabricated and assembled, and- 10 which conducts the desired shredding and blending action and the subsequent solvent "action in a highly efficient and satisfactory manner. Other obj'ects and advantages of" the present invention,'particularly as 'exem-y 15 plified in the aforesaid illustrative embodiment ofthe same, willin' part be pointed out in detail hereinafter and will in part be obvious to those skilled in the art to which Y the present invention relates.

In the accompanying specification I shall describe and in the annexed drawingsshow an illustrative embodiment of the present invention; It is, however, tobe clearly understood that my invention is not limited to the specific embodiment thereof herein shown and-described for purposes of illustration only. Y Y n Referring to the drawings, in which I have shownthe aforesaid illustrative embodiment of the present invention:

Fig. 1 is a top-plan view of such embodiment; r i

Fig. 2 is across sectional view of the same taken along line 22 of'jFig. 1 of the drawlngs. I r Referring'now to the aforesaid illustrative embodiment of the present invention, and

with particular reference to the drawings il-' 'lustrating the same, .10 indicates'a tank or S so as to initiate the dissolvingaction'in; a most efiiclent manner, the solvent action.

other suitable container in which the operativeparts of the aforesaid illustrative'embodi point 28 referre'd totowards theinner edge or, other source 'of power, not here deemed necessary to be shown, is preferably of a construction which adapts it readily to re ceive the shredded ordisintegrated material coming'from' the vshredder or disintegrator being further facilitated 'bythe functional relation between the rotor Rand the de-L 'flector "D. i

For this purpose therotor R may, forexample,comprise the followingconstructiom 10 indicates an inner supporting ringwhich, is keyed .or'otherwise suitably attached to the shaft T which maybe rotated from anyisuit- 365 able source of power not here deemed neoes-L; sary to be-sh'own For this purpos-I ma'y,

for x e p y tlat/key 12 which iliesbetweenithe keyway .13 of shaft T and the' ke way'l ofthe inner 'supporting ring -10*.' P 1 he inner supporting ring 10v is prefer ably slotted, as at'20to receive'the blades here I generally designated by reference character 21. While the blades mayihave various shapes and may differ in minor. details, whilestill remaining Within the scope of the present invention, I prefer that they shall have somewhat the form shown 3 in the drawings 7 in which each blade 21' isofgenralcurvilinear shape. The shape of the blank;from? which each of-the blades may be 'made may readily bedetermine'd fromthe formofthe 7 blades, as illustratedvin Figs. 1 and 2 of'the drawings. i

It will be noted that the blanln no less-than V the blade, increases moreor less continuously ;and;more orlessrectilinearly in width from its inner edge22 to a point23, not'far. removed from its outer edge 24 where the widthidiinin ishes more or less curvi linearly until the outer-5 edge 24 is reached. From the 7 Point I 23 referred to towards the outer edge 24, thetop V edge 25 is conveXjly curved,iwhile from the .22 thetop edge 26, is substantially straight or I prefer also that the bottom I rectilinear. V V edge 27 of each'of the blades 21xshall-be sub stantially straight or rectilinearand shall be which may be soldered or otherwise secured to the slots or keyways28 of the respective rings, thus binding the structure together in a unitary rigid manner. t may here also be stated that the inner edges 22 of each of the blades 21 may be soldered in the slots 20, additional strength being given to, the blades 2 by their union with the deflector ringSO now to be described. v a As stated, the blades 21 need not have the shape just described. 'Theymay have any suitable construction, the point to be clearly p kept in mind being, thatirrespective of the shape of the tank and blades, the latter must not be spaced toogreata distance from the ubottoin of. the former for the-reason that the ;b1ottom.of the; tank plays avery important part inthe mixing; operations of the devices -,o'f thejpresentinvention. I c 5S0, too,'thetops of the blades need not be :straight andthey may be perforated, if dersired, to increaseitheir mixing efiiciency.

:For this purpose the deflector ring 80 is some- ,=wvhat -rconvexly :curved and is upwardly V -thimble62 keyed as by.- theineans 63t0,the

afcurved from-:its outer edge 31;to its inner edge 532 which projects somewhat above the 7 0 points 23.0f-each of the blades 21. It may ez he're be stated that-the deflector ring 30 may x-be-soldered to the upper edge portions of Reach-er the blades 2110i may. be weldedrheremto.

blades 30 in the manner described between the rings 10 and 20 and by perforating the same in the manner illustrated where the perforations are indicated by reference character 31, I may greatly increase the efiiciency' and the speed of the mixing or melting operation which is eifectedby cooperation of the deflector here generally designated by reference character D with the rotor which is intended to lie within the opening 41 in the deflector D.

For this, purpose .one group of the blending elements, here designatedby Thed'eflehcjtor ring 80 is joined to the upper {edgejportions2 5 of each of the blades 21 between the points 23 and the outer edges reference character 60, may be carried soas to rotate with the rotor R." For this purpose the elements 60 may be carried by a plurality,

such as four, cross arms-61 which may form a partof or be properly secured to a sleeve or There-tarry blending elements 60 a1'e"p'i'"ef.' .195 erably of general cylindrical form and may be either made up in a single sheetpointed until the desiredforin if the sheet has been stamped or otherwise manipulated-to provide the shredding or disintegrating; point-s 6051100 on oneor both 'facesthereoflgor else the sub- :stantially cylindrical rotary disintegrating or shredding element 60; may beformed in o uadreds and in that form havingalready been provided with the' teethor proje'ctionsr105 GOseCuredt-O thecross arms 61. In whichever manner the substantially cylindrical blending elements 60 are "constructed, they. may be secured to'lthe cross arm 61 in any suitable manner.. For exam-inlo ple, the cross arm 61 may be provided with the grooves 61' Within which the elements 60 may be securedas bysolderingorelse the upper edges of the element '60 may be cast into the material of which the cross arms61e3-115 aremade. I a :The remaining orstationary' set of blending-elements, here generally :designatedby referencecharacter 70, maybe secured to the arms 71-which are in turn secured to the top 5120 portion of the deflectonD. The stationary elements 70, like the rotary-elements 60, are preferably of substantially cylindrical form and may be given such form either byband- Y inga single; sheet of metal of. which thepar-ilaa ticular element 70 is tobe made, preferably after the-same has had struck 'up therefrom the teeth 70, into si'ibstantially cylindrical form, or such element may-befconstructe'd of 'a series of 'quadredssuit-ablybanded, pref-zine erablyafter they have been provided with the teeth 70. Also like thestationary element 60, the rotary or'movable element 70' may be secured in-thearms 71 preferably 1 within the grooves 71with which such arms 'are'provided and within which the lower edges of the stationary element 70 may be secured, as by soldering or suchlower edges may be cast into the material of which the arms 71 had been made:

Theteeth 60" with which the elements '60 are provided, as well as the teeth 70' with which the elements 70 are provided,are preferably arranged in'd1agonal llnes or 1n staggered relation over the, sheets of metal from which they are struck. Except in the case of the outermost and innermost .of the stationary elements 70, l1ere designated by ref erence characters72 and 73, which have the teeth. or projections .70 only on the inner face of the one and theouter face'o f the other, such teeth'or projections arelpreferably providedon bothsides' of the nested elements 60 and 70. v 7

This completes the description of the aforei said illustrative embodiment of the present invention. Themanner of constructing, and assembling. the device constituting such embodiment will, it is believed,"'b,e clear from the foregoing description. Likewise the manner'of operating the device will be similarly clear from the foregoing description but may be briefly summarized as follows:

Assuming that it is desired to makea solution of a'diflicultly soluble materiahfor ex:

' :ample-,a-fibrous material, in a solvent, such material is discharged in lump or other suitable form into the tank 10 after the rotor "carried by the shaft 10 hasbeen started into operation by starting the motor, not here deemed necessary to be shown, or other device which is adaptedto impart to the rotor R the desired speed of rotation. V

The material discharged in lumps overthe blending device S will be caught between the teeth 60 and of the rotary and stationary elements 60 and 70, respectively. There such material will be thoroughly shredded or disintegrated and in such shredded-or disintegrated form within the fluid of the tank 10 discharged downwardly between the blades of the rotor R. Here'the disintegrated and fluid material will be thoroughly blended f and the solvent action started in an efiicient manner. The mixed partially orcompletely dissolved blended material and fluid will be.

laterally discharged from the rotor B through the deflector D.-. Here the solvent action will be completed or, if already comrotor R, thus facilitating and increasing the efficiency of the solvent. action-.

This operation may be continued'as long as desiredpdepending uponthe amount of material tobe shredded and disintegrated and particular solvent employed.

bodimentof the present invention. It will be noted that the device is simple in construction and may be readily and conveniently fabricated and assembled. and that it is highly efficient inoperation. It will be noted that by means of the device the desired blend T hiscompletes the description of the mode of operation of the aforesaid illustrative em- .70 I ultimately dissolved, and depending also uponethe diflicultyattending the Solution of r the disintegrated or shredded material in the ing action. to facilitate solution is rendered possiblein an altogether'simple and efficient V manner and that the solvent action itself is greatly facilitated by reasoniofthefunctional arrangement of the three main parts of the device, namely, the blending means S, the rotary stirring means R and the stationary mixing means D. 7' g f Other superiorities and advantages .of, the

devices ofthe presentinvention, particular.
